因此不需要等效的TEMPERATURE约束。实现工具在时序驱动算法中不使用'set_operating_conditions'。
这通常通过设置适当的时序约束来实现,例如使用set_operating_conditions命令来定义不同的PVT条件。tcl # 示例:设置典型工艺角的时序约束 set_operating_conditions -name typical -library {typical_lib} -max_delay {max_delay_file} -min_delay {min_delay_file} 注意:这里的{typical_lib}、{max_delay_file}...
set_operating_conditions -process maximum Junction Temperature: Leakage current increases exponentially with Junction Temperature which results in higher Static Power. Junction Temperature depends on various factors: the total power of the device, the cooling system, board selection and ambience. ...

Including operating conditions such as voltage settings, power and current budgets, and operating environment details. Switching activity rates for individual nets and pins、block RAMs, DSPs, and transceivers and global set and reset signals.
For Linux operating systems, licensing environment variables cannot be set using the Vivado License Manager (VLM). The environment variable fields are read only, so they are grayed out and there are no Set buttons. The environment variable must be set using the appropriate OS shell and commands...
UCF 约束默认不对异步时钟间路径进行时序分析,而 XDC 约束默认所有时钟是相关 的,会分析所有路径,可以通过设置时钟组(set_clock_groups)取消时钟间的相关性。 下面介绍一下在 Vivado 中添加 XDC 文件以及加入约束命令的方法: 首先在 Project Manager 中展开 Constraints 类,选择 Add Sources 即可添加或者新建 XDC ...
